Process Description
Potassium permanganate has the chemical formula KMnO4 and CAS number 7722-64-7. It forms slender, dark-purple to black orthorhombic crystals with a blue metallic luster. It is non-combustible but is a strong oxidizing agent and may cause combustion or explosion on contact with organic or readily oxidizable substances. It has a sweet, astringent taste, is soluble in water and alkaline solutions, and is slightly soluble in methanol, acetone, and sulfuric acid. Its aqueous solution is reddish purple. It is corrosive and toxic and irritates the skin and mucous membranes. Potassium permanganate is widely used for disinfection, sterilization, water purification, chemical analysis, pharmaceuticals, and organic synthesis, where it functions as an oxidizing, disinfecting, and bleaching agent.

Technology comment
Electrolysis is the core mainstream industrial technology for the production of potassium permanganate. It uses potassium manganate solution as raw material for electrolytic oxidation. This process has high technical barriers and accounts for more than 99% of the domestic potassium permanganate market. This dataset represents the mainstream technology: manganese powder and potassium hydroxide are oxidized at high temperature to form potassium manganate, which is dissolved in water and then undergoes solid-liquid separation by press filtration. After dissolution and electrolysis, crude potassium permanganate is obtained, and the finished product is obtained through refining, recrystallization, and drying. The chemical reaction equations involved are mainly: 4KOH + 2MnO2 + O2 = 2K2MnO4 + 2H2O; 2K2MnO4 + 2H2O = 2KMnO4 + 2KOH + H2.
